Question

a company needs a function to calculate employee bonuses. the function should accept the employees salary and years of service, with a default bonus rate of 5%. explain what parameters you would include, which should have default values, and why using keyword arguments might be helpful when calling this function.

Explanation:

1. Parameters to include: The function requires three parameters: employee salary (a mandatory input as it's unique per employee), years of service (mandatory to account for potential service-based adjustments), and bonus rate (to set the percentage used for calculation).
2. Default value assignment: The bonus rate should have a default value of 5% (0.05 in decimal form), as specified in the requirement. This means users don't need to input it unless they want to override the standard rate.
3. Keyword arguments benefit: Using keyword arguments when calling the function makes the code more readable and less error-prone. For example, calculate_bonus(salary=80000, years=5) or calculate_bonus(salary=80000, years=5, bonus_rate=0.07) clearly shows which value corresponds to each parameter, avoiding confusion if parameters are ordered differently or if the default rate is being overridden.

Answer:

• Included parameters: Employee salary, years of service, bonus rate.
• Parameter with default value: Bonus rate, set to 5% (0.05) by default, since this is the standard rate specified, and only needs to be changed for non-standard cases.
• Keyword arguments benefit: They improve code readability by explicitly linking values to their parameters, reducing errors from misordering arguments, especially when overriding the default bonus rate.
